- According to the UN, nearly one in three people worldwide live in a country facing a water crisis, and less than five percent of the world lives in a country that has more water today than it did 20 years ago. Lana Mazahreh grew up in Jordan, a state that has experienced absolute water scarcity since 1973, where she learned how to conserve water as soon as she was old enough to learn how to write her name. In this practical talk, she shares three lessons from water-poor countries on how to save water and address what's fast becoming a global crisis.

Animal agriculture uses more water than any other area of human activity. In California alone, the animal agriculture industry accounts for 47% of total water usage. If you want to save water, eat less animal products.
If you eat less meat you have to eat more plants. Plants take water too. Highly doubt the amount of water used for animals is much different than water used for plants after you account for the differences in energy density and water content from each source.
Actually, it takes approximately 13 times more water to raise livestock for human consumption than to grow plants for the same purpose.
Pat MaCrotch Nah because what is the life stock eating? So even if a plant needs as much water as a cow (which it probably does, right? Idk), the cow eats tooons of corn or whatever. Uses waaay more water :(
100% this! Taking a shorter shower, etc. isn't even in the same league of environmental impact compared to eating less animal products!
alina laubten No alina, that's not correct. You have to give water to the cow as well as the plants. As you move up the food chain, you lose energy in the process. Eating plants is magnitudes more efficient.
Every day as a vegan you save 1,100 gallons of water. Animal agriculture is depleting our recourses rapidly. Eating less animal products will do more than taking a 5 min shower.
Sarah Spiekermann yes^^^
Looks like not eating meat affects spelling as well.
okay?

The shower head scheme in Melbourne is actually statewide through Victoria, I live in the central Victorian region and all our taps and showers have flow reducers in them. I think Western and South Australia have followed suit. I think the billboards showing water capacity are good, but it's also a listed feature in newspapers and TV news, etc. I have also taught my girls who prefer baths, to turn off the taps when the water level reaches the Ball of their feet (under the base of their big toe), as that is deep enough to submerge the whole back of their head when resting on the base of the bath while keeping their eyes clear by about 1cm. They do have to tilt their forehead under to wet/rinse, but they can stay in as long as they like without adding more water. I would have no qualms about drinking recycled water - the astronauts do! But I don't know of anywhere in Australia that has it for drinking purposes, just for watering council land/reserves.

I didn’t expect anyone to notice that.

In Australia, most people that can afford it are installing rain water tanks with pressure pumps and water filters. We personally have 11000 ltr capacity which gives us enough water for 3 months without rain and allows us to Water plants, have showers, brush our teeth, wash our clothes and generally have a healthy life and, it is powered by solar energy. When our water runs out, (it sometimes does) we can turn a tap on and enjoy water from the town supply which is half as good quality.
Really well spoken. The speech is full of facts and is really insightful. Kudos!!
Greetings from Cape Town. 😅 Yeah the water crisis is pretty hectic. They will close all taps soon. We'll need to start collecting water from water distribution facilities.
Sad dude... Best of luck...
There’s a growing need to be very aware about our situation
So, being from Cape Town, this has been reduced to 50 litres a day now. Cape Town will turn off water very soon. Very very soon, within the next two months.
is there a solution in the works or are you just screwed?
Peng-Ta Wang Saw this on the news today. Terrible!
SuperAtheist Desalination Plant is Cape Towns best option
Such situations are regular for where I live, in Kolhapur, India. Rains have become unpredictable, and our water storage capacity only gets the city and surrounding suburbs running for barely a year. So by June, if it doesn't rain, the situation gets really bad
SuperAtheist
The solution is vegansim.
And yes, before some triggered person @‘s me, ask yourself this question. Is taste and convenience THAT important in light of the health and wellness of the earth, it’s animals and our future children?
Earth is a closed system. Water is recyclable. There's no water scarcity problem. It's how humans manage it.
nail on the head
Globally true. Locally not always true.
Isn't that kind of the point of the video?
Rainfall patterns affect how quickly aquifers/reservoirs are refilled. With climate change, some places are already receiving less consistent rainfall. I recommend the book 'when the rivers run dry' to learn more about how serious this issue is.
Perfect
I'm living in Bloemfontein,RSA and people waste water as if there is no crisis in the Western Cape right next door; the hospital I work in, as an example, has so many leaking taps (that can be easily remedied by closing it properly) and other plumbing issues that cause significant water losses over time but don't seem to bother management even when reported- I'm terrified of water running out here but I'm not sure where I could start helping except in my own capacity- this talk was great though citing examples of water scarce countries 😕I feel like we'd only take widespread action here when it's too late
Interesting talk!
Offering solutions originated from third-world countries and encouraging other countries to follow the suit is genius.
Wonderful message
Nice presentation.
When it comes to private buildings, earthships are using water very efficient.
It is interesting lecture that to aware the people and save what they have.
Great talk 🙂
Being in the navy taught me the method of taking a submarine shower. Get wet. Turn the water off. Wash yourself, taking as much time as you want. Turn the water back on and rinse the soap off. Another method is to pee in an empty laundry detergent jug. It'll fill up after about 4 times then pour in in the toilet and flush once for 4 pees.
I adhere to the maxim: 'When it's yellow let it mellow, when it's brown flush it down." If necessary I dilute the mellow with rainwater :-)
Lots of talk about conserving water, but only one brief and narrow example of recycling water. The former is good, but you need to do some work on the latter. Gray water systems can replace residential sprinkler systems. There are a lot of low-tech approaches that you can do at home as well.
For example, I flush my toilets with used shower/bath water. Plug the drain and collect the water in (appropriately enough) cat litter bottles. We have high efficiency toilets, so each bottle is good for about a flush and a half. Each shower is good for at least 3 or 4 flushes. The supply line is turned off, and I keep the tank open to refill. (Yes, you can pour the water into the bowl, but this way there's no splash.) Do the math: 1.5 gallons per flush (average), at least 2 flushes per day (low estimate), 365 days per year (rounding down, duh) = about 1100 gallons per year saved.
Our laundry is done with Ecos (plant-based detergent). All the water is filtered of lint, then goes out to rain barrels which water the lawn. We have an average washing machine. It's not high efficiency, but not a dinosaur either. Uses 26 gallons per load (12 gallons to wash, 12 gallons to rinse, plus 2 more gallons during the spin cycle to push the last of the detergent out). Picture a 55 gallon drum. I can fill two of them almost to the top by the time we've done the white, lights, darks, and pink/purple/reds (because I have a daughter). But it all goes to the lawn and becomes local ground water instead of a waste water treatment plant and into the river and out to sea.
Hi,greetings from Taiwan,nice to listen the very best speech here .
Well said! Indeed I believe that a big part of the solution relies in all of us instead of waiting for decision makers to do something. Thank you for this valuable three lessons!
very innovative
and inspiring
Woow that's a great presentation ❤
Very interesting concepts, I’ll take them into mind
The problem lies with corporations taking control of natural resources like water (because we live in a competitive and profit-based system) and the wasteful and polluting practices of large industries and agriculture.
The 90 dislikes are from the people who brush their teeth wth the tap running
Hey from Cape Town yeah it is big problem (obviously)
Saving water is so important matters,all of us in the world have to pay attention to the issues
Nice information.
In the article, Day Zero means:
the time when people will be using bottled water only
O the time when most of the water will be unsafe to use
-->the time when the water will not be available for use by residents of the city
• the time when the supply of water will be renewed
• the time when the usage of water dropped from the hundred-liter limit a day to 50 liters
No mention of "Greening the Desert" from a Jordanian speaker covering the subject of water? Strange.
Im raised in jordan too

I hate sand, it's coarse and rough- Anakin Skywalker
An update on Cape Town... We are now down to 50l per person per day, day zero is upon us and we have been taking the necessary steps to conserve our limited water, we are ordered to go to points to collect 50l of water a day and queue up to three hours for water collection, I never realised how lucky I was to go to my tap, have water running out of it and be able to drink that water, now we cannot do that. Just a little update on Cape Town
The Greatest Water speech of the ERA !!!!
If it's yellow, let it mellow.
If it's brown, flush it down.
Devil's Advocate I piss up my fruit tree's they grow 3 times faster!
Words to live by.
One simple way: when/where reserves are low, charge more for water.
The market is a wonderful thing.
Wow 💧
I'm not going to "save water". I pump water from my own garden, after shower it gets back into ground after treatment. Nothing is lost.
👏
I have a wash once every month whether I need it or not!
Ugggh...bet you have a THRIVING social life.
Im the same I only wash when I have spare time & or the local reservoir is full.
Abdullah ibn Amr reported: The Messenger of Allah, peace and blessings be upon him, passed by Sa’d while he was performing ablution. The Prophet said, “What is this extravagance?” Sa’d said, “Is there extravagance with water in ablution?” The Prophet said, “Yes, even if you were on the banks of a flowing river.”
Source: Sunan Ibn Mājah 425
Grade: Sahih (authentic) according to Ahmad Shakir
Messenger? This is important stuff here. Next time use Western Union or send a text message.
Which solution proposed in the TED talks By Lana Mazareh and Deepika Kupur do you think would be most helpful for the city of Cape Town?
(Solution Choice - 1 point, explanation/ example/ evidence - 3 points)
According to Deepika Kupur's ted talk, she mention SODIS which is used for purify to water but it works slow. But there is a new method called photocatalysis which is speeding this SODIS process.
I have a habit of conserving water that said no matter how much you conserve you will always be asked to conserve. Reason is cities will approve more building and welcome more residence for taxes and profits .My city has approved housing approved home building to increase population by 30% 25,000 more residence during drought time .
How sustainable are these solutions though? Is there a way to adjust the system to conserve and collect water without replacing all of our products and putting more waste into the environment?
this video is assign as my English assignment in audio form..
Its so hard to be a child whose heart burns seeing water overflow but could not do much for the whole country, just for my own house....from India.
“You cannot do all the good that the world needs, but the world needs all the good that you can do” ❤️✨
we are in drought in the uk. i am going to be careful of water usage and shower with a bucket so i can water my veg with it. we cannot be complacent or selfish. we already use a bucket to wash dishes so we pour out the water for the plants
hay quá ạ 😘😘😘
In the article about Cape Town, who in your perspective was harmed by strong government measures to reduce water usage? (Harmed person/people: 1 point, Evidence and Explanation: 3 points)
Cape Town's 4 million resident harmed because government reduce their water usage 1.200millon liter to 516 million liter a day. They are using 50 liter per a day its only one-fifth of average Canadian residents. Also city resident reduced their water consumption by 44 per cent
Where is Deepika Kurup from, and what is the name of her enterprise?
She is from India. She start to research how to solve global water crisis at 14years old. Her interprise is Catalyst for World Water.
i live in cape town ... we're moving towards 50 liters now ...
Julia Grundling how then you complete household work without water
Ok, czy ktoś wie jaka jest sytuacja w Polsce?
"Shower is my sanctuary" is as much valid argument for not saving water as "I love steaks" is for not being vegetarian.
We can save water by other means too ....Taking shower with Cleo shower filter saves .Check thisczcams.com/video/NXUYnHNVa48/video.html
I liked
your comment
Growing feed crops for livestock consumes 56% of water in the US, and only 5% of total water consumption if for private homes. 6000 gallons of water are needed to produce 1 kilo of beef. Nothing COMPARES to animal agriculture. California, for example- according to the Pacific Institute, agriculture accounts for 80% of California's total water usage, including alfalfa, the crop that uses the most water, and which is used to feed farmed animals.
Water is not lost forever, still part of hydrological cycle. Either build a expensive water grid or cheap to purify: recycle grey water for non potable use like flushing the toilet, watering plants etc. if you don’t like it then reinject into the aquifer to increase water table.
Singapore recycles even black water to drinking water.
I made it with Avasva handbooks !
They try to bring in new kinds of technology to pull water directly from air and that's the reason everyone has water scarcity.
I am going to get first place in my school for waste management , cause I'm going to explain about water 🤓🏆🎖️🥇
Why did she say nothing about meat industry?! Where are your priorities?
What did Capetonians do to prevent the catastrophe of Day Zero? Provide three examples. (2 points each for the example and an explanation of how it can prevent Day Zero)
Capetonians would have to stand in the line for water
Soldiers would have guards to water tanks
when these are will happen Cape Town residents won't have access to water and people can fight for water. It can start to war between army and residents.
Which solution(s) proposed in the TED talks by Lana Mazareh and Deepika Kurup do you think would be most helpful for addressing issues related to sustainability (air pollution, energy consumption, waste management, deforestation, water problems etc.) in your home country? Write a short paragraph describing the issue/s relevant to your home country and the solution/s from the materials that might or might not work. (Issues: 2 points; Solutions and Explanations: 4 points)
Water problems can happen in everywhere. lam from Turkey and sometimes it happens in my country too. Our country is half island, we have experienced water crises. Sometimes they cut our water beause we did not have enough water and our government had similar solution with Singapore. They built large barrages to keep rain water and it effect our water accesibility, our water limit and social life. People jogging, riding bike and camping around barrages.
I watched this video with all the lights on in my house and with all the taps on.
I lied about watching the video
Somebody needs to invent stillsuits
If you build sufficient dams and other water infrastructure you will have plenty of water. People tend to forget that their grandfathers built dams and wells that they are still drinking water from. If you want water for your community, there are plenty of ways to get it. If you build it, they will come to drink from it.
What pisses me off is in India is, Everyone takes about water conservation and saving the environment but pollute our rivers and lakes. I live next the largest lake in Bangalore(my city) but it is totally polluted with industrial waste and sewage water. We get our water in trucks even thou we are right next the largest lake in the city. It is just sad.
And it will only get worse until a generation decides to make change.
Can we save water??? Some people don't even have or know what water is..
For those people doing this for their assignment at school, just open the Transcript instead of watching the video.
It doesn't seem that shower water really gets that dirty. Perhaps it could be continuously recycled as you shower. You could shower for hours. Also, water doesn't have to be perfectly filtered for toilet use. Dishwasher water with the soap still in it would probably be fine.
Dishwashers basically do this. They only use a very few gallons of water, continuously cycling it back over the dishes.
For toilet use, try bath water. It's right in the same room. I describe methodology in an earlier comment, but the short version is simply this: Shut off the toilet's supply line, keep the lid off top of the toilet, and you can refill it with bath water.
Who's here from Mr. Salladay's class
The surface of the earth is 71% water. There is no water shortage. Only a shortage of humanity and abundance of greed.
Go drink some salt water you just described and prove us all wrong ;P
Never heard of desalination?
headcrab4 Israel is leading the world in desalination. They are a desert country just like this girl's country, except instead of a water shortage they have a water abundance! It's amazing what a little brain power can do.
Art Of Warring however desalination can be really expensive, sadly a problem in our modern world
Never said it was impossible, but it's a lengthy and costly procedure to do on a large scale. A process that many underdeveloped countries don't have access to. If saltwater was as easy to convert to drinkable water as you claim, this wouldn't even be a problem in the first place.
I love how she touts that by the end of Australia's drought 1/3 of people had rainwater collection tanks in place.... Not in America! That's illegal in a lot of states. Antienviornmentalism at its best. ;)
orbix Is that a joke? Why would any govt ever stop people from rain water harvesting? Rather I've always seen govts encouraging it, as it saves cost of transporting the water back to cities from rivers, reservoirs and lakes.
I truly wish it was....
Upon researching though, a lot of these states have changed their laws after a backlash from people. Here is actually an updated list of each state's laws concerning rain water collection. When this was an issue like 10 years ago, people were actually being imprisoned for doing so. Glad to hear they are finally doing something to change those absurd laws.

Why don’t they just waterbend the water out of the air
Kiwi_ Dont_fly
Anyone here explain me in hindi ..??i want this in hindi
Southern California purifies all of its waste water to recycle it into the system that provides home tap water.
After using sand as for Ice Bucket Challenge, I am sure, you have used more than required water to wash and wash your hairs. It was better to do it with Ice. Thank you, Lana Mazahreh.
I made it with Avasva solutions.
Water shortages are a lie in the U.S.A.
sibling
She needs to watch cowspiracy... skipping one burger can save as much water as not showering for 3.5 weeks. Go vegan (that's only one of hundreds of reasons).
chickpea and your vegetables don’t need water to grow
KOLO69 and who's going to eat tons of these vegetables before you kill it so you can get a few calories out of it?
Or people can just eat less meat or start to consume proteins from vegetable sources like almonds, soy, peanuts.
Либо вы живёте в тепле и уюте, но без воды, либо постоянно замерзая по голову в снегу. Я выбираю второй вариант ))
Everyone is saying the same thing - give up meat and dairy and you'll be part of the solution rather than part of the problem. A meat based diet uses at least 20 times more water than a plant based diet. Most people know this but are too stubborn, selfish and egotistical to change. People hate feeling they're being dictated too, even tho they're not. It's simply common sense. People say they want a future for their children but fail to put their money where there mouth is. It's very simple. Go vegan, live at least 10 years longer and you'll be in less trouble with the Gods when you die too. Do it!
Please conserve water. Us salamanders need a place to live, too.
Yes, just dont mention animal agriculture, that would make people uncomfortable about their eating habits and we dont want that, do we?
Haha just drink Juice instead :^)
Noice
After that sand bucket challenge probably you took long time shower to get rid of that sands from your body tho 😏
Am from Cape Town, you didn't do your research well.🤐
Why nobody talks about meat consumption?
supbbb
Let's recycle less to save water.
Wash your face twice? What? Face washing takes a liter or two. Flush takes 3-8 liters. How can you not wash your face 50 times?
Reverse osmosis all the water
easy guys just dont shower
Fix nature and we will have water
I was forced to watch this
First one😎😎😎
Bashir Hameed no one cares little kid
GO VEGAN OMFG
There is no way, of course, she is going to mention Israel, one of the most amazing success stories when it comes to solving water crisis.
Does it have to do with their almost 10% vegan population?
Dan Cenow
No.
Ah, I thought that was the logical conclusion. My bad.
Maybe it's because they massively restricted access to water for Palestinians? ;)
Dan Cenow
It was a combination of public awareness, large scale recycling and sea water purification.
i just stopped drinking water. All i drink is diet coce, for the sake of the environment
SnowmansApartment Welcome to the world of obesity.
SnowmansApartment You need 2 liters of water to make 1 liter of coce
SnowmansApartment Way to go 👍🎶 H2o has got to go Hey Hey Ho Ho 🎶
SnowmansApartment Been there. Cola just doesn't hydrate you very well. You'll start experiencing dehydration symptoms within a few days.
Assel Kondybayeva Then Coce winns, against apple juice.. because one kg of apples needs apparently 822 liters of water 🤯..

I bathe once a month.
I drink my own urine.
I don't flush the toilet when I only pee.
That's my 3 tips.
Lol nub
I bathe in my pee and I never flush my toilet. Try getting to my level.
Trump does something like that, but it's not his pee.
EMPOWER IS NOT GONNA DO IT
We do need to reinvent the wheel.
We need to reinvent the plumbing code.
No other way out!
Capetown, SA Ration of 87L/day is too much water. I can do it with less.
We now have the technology to do this.
